WINDMILL.

Application filed March 18, 1925. Serial No. 16,415.

provements in WVindmills, of which the following is a specification.

The object of the invention is to improve the construction of windmills.

' Another object of the invention is the provision of means in windmills whereby the wind wheel may be mechanically turned or adjusted against the wind.

A further object of the invention is the provision of means for holding the wind wheel in adjusted position against the wind.

With the above general objects in view and others that will appear as the nature of the invention is. better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claim.

In the drawing forming a part of this application, and in which like designating characters refer to corresponding parts throughout the several views,

Fig. 1 is a side cross-sectional view through the windmill embodying the present invention;

Fig. 2 is a fragmentary view, partly in section and partly in elevation, taken on lines 22 of Fig. 1 looking in the direction of arrows;

Fig. 3 is a sectional view taken on line 3 -3 of Fig. 1 looking in the direction of arrows; V

Fig. 4 is a top view of a part of the mechanism of the windmill;

Fig. 5 is a cross-sectional view taken on line 5-5 of Fig. 4; and

Fig. 6 is a transversal view across the shaft illustrating the braking mechanism.

The invention embodies floor 10 supported on beams 11 and. upright supports 12. Above said floor 10 are supports 13 holding platform 14. Said platform 14 at its center has a bore 15 wherein sleeve 16 is positioned for the purpose of lining said bore and strengthening the structure, said sleeve being integrally formed with a tabular disk 17 which is mounted upon the platform and rests in the circular recess 18 made therein, the upper surface of said disk remaining flush with the upper face f said pl tf rm.

Said disk is firmly fixed to the platformlby means of bolts 19, the lower side of the platform being provided with sockets 20 within which nuts 21' cooperating with bolts 19 are enclosed.

A turn-table 22 is positioned upon the platform 14 and disk 17 and is rotatably mounted thereupon. Centrally thereof and clownwardly depending, therefrom the turn-table is provided with an integral sleeve 23 which passes through sleeve 16 and is adapted for rotation therewithin. Ball bearings 24 are provided upon platform 14 and disk 17 facilitating the turning of the turn-table 22 upon said platform.

As plainly seen on Fig. 1 the lower end of sleeve 23 projects downwardlybelow the end of sleeve 16 and below the lower plane of platform 14. The projecting end of said sleeve 23 is adapted to receive thereupon the spur gear 25 which is keyed to said sleeve 23. Said projecting end of sleeve 23 at two diametrically opposite points on its periphery is reduced in thickness as at 26, Figs. 1 and 3, substantially assuming an elliptical form in cross section on horizontal plane as plainly seen on Fig. 3. The spur gear 25 has an elliptical bore within which said elliptical end of sleeve. 23 is adapted to fit and to be rigidly fixed therein. Thus, it will be seen, onturning spur gear 25 the turn-table 22 will turn therewith.

Mounted in step-bearing 27 and in the socket 28 made in the platform 14 is up right steering shaft 29 with a steering wheel 30 mounted thereon. Bracket 31 secured to the lower face of platform 14 encloses shaft 29 and provides a bearing for pinion 32 which is keyed upon shaft 29 and meshes with spur gear 25.

Rigidly mounted upon turn-table 22 are standards 33 providing bearings 33 for horizontal shaft 34, said shaft having at one of its ends a wind wheel 35 embodying conventional vanes or paddles 36. Adjacent the bearings 33 collars 37 are provided upon the shaft for preventing any longitudinal creeping movement of the shaft on said bearings. A bevel gear 38 keyed upon said shaft meshes with a bevel gear 39 which is keyed to the upper end of vertical shaft 40.- Said latter shaft has a collar 41 rigidly mounted thereupon whereby the'shaft is supported upon the upright bearing 42 which is provided with a central bore registering with the bore in the turntable 22 and sleeve 23, as plainly seen on Fig. 1. Said shaft 40 extends downwardly through the said bores beyond the lower face of spur gear 25 whereat it has section 43 joined thereto as at 4:4. Said section at its lower end is supported in a step-bearing 4:5 and has a beveled gear l6 meshing with a bevel gear 47. Said latter gear is keyed to horizontal shaft 48 which is supported on standards 49. Said shaft 4-8 ha an idler pulley 50 and a rigidly mounted pulley- 51, from which latter pulley the power is trans mitted to-any machinery, not shown and which may be positioned below floor 10, through and by means of belt 52.

By turning the steering wheel 80 the pinion 32 and spur gear will be rotated and in consequence thereof the turn-table 22 with shaft and wind wheel 35 will be bodily turned. Thus the wind wheel 35 may beturned against the direction of the wind.

For the purpose of clamping turn-table 22 and preventing its rotary movement when proper adjustment of the wind wheel 35 has been made, clamps are provideth said clamps being swiveled on pins which are affixed to rods in any suitable manner. Said rods have enlarged threaded portions 56 which are received in threaded apertures of the outer ends of brackets 5'7, the other ends of said brackets being atliaed to the under face of platform 14 as at 58. The lower ends of rods 55 are provided with hand wheels 59 by means of which said rods are turned for tightening clamps 53 to the face of turn-table 22 or for releasing the frictional contact therewith as is obvious. For further guiding said rods brackets 60 are mounted outhe peripheryof platform 14;. For preventing clamps 53 from turning and consequently from changing their relative operative position in respect of the turn-table 22 when rods 55 are operated, arms or flanges 61 integrallv formed with said clamps are provided for contacting with the platform 1a on its-periphery.

Braking mechanism for the windmill ineludes pulley 62 keyed upon the shaft Bat and brake-band 63 which passes over said pulley, one end of said brake-band being secured to turn-table 22 as at 64. The other end of said brake-band is anchored to lever 65 as plainly seen on Fig. 6. One end of said lever (35 is pivoted to arm 66 projecting from plate 67, said plate being riveted or in any other manner secured to the turntable 22 and projects therefrom beyondthe periphery thereof. The other end of lever is pivoted to threaded rod 68 which passes through an aperture made in plate 67 which rod is adapted to receive a hand wheel 69. By screwing the hand wheel-69 on said rod 68 lever 65 is drawn downwardv which in turn pulls on brake-band 63 which frictionally contacts with pnllev 62.

lVhile there is described herein a preferred en'ibodimentiof the present invention, it is nevertheless to be understood that minor changes may be made therein without ('lepartzingfrom the spirit and se pc of the invention as claimed.

What I claim as new is:

In a winchnill, a platform, a disk thereupon, a sleeve in saiddisk, saidrsleeve passing through a central bore in said platform. a turn-tal le on said platform, a sleeve in said turn-table, said sleeve passing through thefirstmentionedsleeve, the lower, end of said second namedsleeve projecting beyond the lower plane of said platform and having reduced portions at two diametrically opposite points on its periphery, a spur gear, saidw spur gear-having an elliptical bore for receiving said projecting end of said secondnamed sleeve. a horizontal shaft upon said turn-table, av wind wheel upon said shaft, a vertical shaft cooperating with said horizontal shaft for transmitting the power therefrom, said, upright shaft passing throughthe said second named sleeve, and means for turning bodily said horizontal shaftv and said'windwheel.

In testimony. whereofl affix my s-ignaturc.
